Browser caches are supposed to make the web faster — and they do, at first. But over weeks and months those cached files accumulate silently in hidden folders on your Mac, growing into several gigabytes of stale data that no longer speeds anything up. Slow page loads, pages that look broken, or login sessions that refuse to clear are all common signs your browser cache needs a flush.
This guide covers exactly how to clear cache on Mac for every major browser — Safari, Chrome, Firefox, Arc, and Edge — with precise step-by-step instructions, keyboard shortcuts where available, and the exact disk paths where each cache lives. It also shows you how TrimyMac's Browser Caches category scans all five at once so you never have to repeat this process manually again.
How to Clear Safari Cache on Mac
Safari
Up to 2 GBSafari is Apple's default browser and stores its cache tightly integrated with macOS's sandboxing model. There are two ways to clear it — through the Preferences privacy panel (which removes website data) or through the hidden Develop menu (which empties only the disk cache without touching cookies or stored logins).
Method 1 — Preferences > Privacy (removes all site data)
- Open Safari. In the menu bar, click Safari then Settings (macOS Ventura and later) or Preferences (older macOS).
- Click the Privacy tab at the top of the Settings window.
- Click Manage Website Data... — Safari will spend a moment loading all stored data.
- Click Remove All in the bottom-left corner to delete all website data, or use the search field to find and remove specific sites.
- Confirm by clicking Remove Now in the dialog that appears. Safari will clear cookies, cached resources, and local storage for all sites.
Method 2 — Develop menu (cache only, preserves cookies)
- Go to Safari > Settings > Advanced and tick the checkbox "Show Develop menu in menu bar" if it is not already visible.
- In the menu bar, click Develop.
- Click Empty Caches. There is no confirmation dialog — the cache is cleared immediately. The keyboard shortcut is Option + Command + E.
How to Clear Chrome Cache on Mac
Google Chrome
Up to 5 GBChrome is notorious for accumulating the largest browser cache of any major browser — partly because it aggressively pre-caches resources from pages you visit and partly because its default maximum cache size scales with the available disk space on your Mac.
Clear via Settings
- Open Chrome. Click the three-dot menu (⋮) in the top-right corner and choose Settings.
- In the left sidebar, click Privacy and security.
- Click Clear browsing data.
- In the dialog, select the Basic tab for a quick clear, or Advanced for more control. Set the Time range to All time to clear everything.
- Make sure Cached images and files is checked. Uncheck Browsing history and Cookies if you want to keep those.
- Click Clear data. Chrome will close any open tabs that are affected and clear the cache.
Keyboard shortcut
Press Command + Shift + Delete in Chrome to open the Clear Browsing Data dialog directly, skipping the Settings menu entirely.
How to Clear Firefox Cache on Mac
Mozilla Firefox
Up to 1.5 GBFirefox uses a self-managing cache that tries to stay within a configurable size limit. Its Preferences panel gives you direct control over the Cached Web Content section with a single-click clear button.
- Open Firefox. Click the hamburger menu (☰) in the top-right corner and choose Settings (or press Command + ,).
- In the left sidebar, click Privacy & Security.
- Scroll down to the Cookies and Site Data section.
- Under Cached Web Content, click Clear Now. Firefox will display the current size of the cache next to the button so you know exactly how much space you are reclaiming.
- Alternatively, click Clear Data... to open a dialog where you can choose to clear cookies, site data, and cached content together.
How to Clear Arc Browser Cache on Mac
Arc
Up to 3 GBArc is built on the Chromium engine, so its underlying cache structure is nearly identical to Chrome's. The UI for clearing it lives inside Arc's Settings panel under the Privacy section.
- Open Arc. Click the Arc menu (the Arc logo) in the top-left corner of the screen and select Settings, or press Command + ,.
- In the Settings panel, scroll to the Privacy section.
- Click Clear Browsing Data.
- A Chromium-style dialog will appear. Set the Time range to All time.
- Check Cached images and files. Optionally include cookies and browsing history.
- Click Clear data. Arc will clear the cache and reload any affected tabs.
How to Clear Microsoft Edge Cache on Mac
Microsoft Edge
Up to 4 GBEdge on macOS is also Chromium-based and shares a similar privacy settings layout to Chrome. It tends to grow a large cache on machines where it is the default browser, particularly when used for Microsoft 365 apps in the browser.
- Open Edge. Click the three-dot menu (⋮) in the top-right corner and choose Settings, or press Command + ,.
- In the left sidebar, click Privacy, search, and services.
- Under the Clear browsing data heading, click Choose what to clear.
- Set Time range to All time.
- Check Cached images and files. Deselect browsing history and passwords if you want to preserve those.
- Click Clear now. Edge will display a progress indicator and confirm when the cache has been cleared.
How Large Do Browser Caches Get on Mac?
Browser caches are dynamic — they grow continuously as you browse and the browser's built-in pruning logic runs infrequently. On an active Mac that is used daily, here is how large each browser's cache typically grows before self-pruning kicks in:
| Browser | Typical cache size | Max observed | Disk path prefix |
|---|---|---|---|
| Safari | 300 MB – 1 GB | ~2 GB | ~/Library/Caches/com.apple.Safari |
| Chrome | 500 MB – 3 GB | ~5 GB | ~/Library/Caches/Google/Chrome |
| Firefox | 200 MB – 800 MB | ~1.5 GB | ~/Library/Caches/Firefox/Profiles |
| Arc | 400 MB – 2 GB | ~3 GB | ~/Library/Caches/Company/Arc |
| Edge | 500 MB – 2.5 GB | ~4 GB | ~/Library/Caches/Microsoft Edge |
If you use multiple browsers — which is common on a developer Mac — the combined total can easily exceed 8 to 12 GB of reclaimable disk space. These caches live entirely inside ~/Library/Caches/, which means they are safe to delete without affecting your bookmarks, passwords, or browser profiles.
Clean All 5 Browsers in One Click
TrimyMac's Browser Caches category scans Safari, Chrome, Firefox, Arc, and Edge simultaneously — no menu-diving in each browser required. See the total reclaimable space before you delete anything.

Going into each browser's settings and repeating the same steps across five different apps is tedious — especially when you just want to reclaim disk space quickly. TrimyMac takes a different approach.
The Browser Caches category in TrimyMac's Smart Clean module scans all five browsers in a single pass. It reads directly from ~/Library/Caches/ for each browser profile, calculates the total reclaimable size, and shows you a per-browser breakdown before you delete anything. You can deselect individual browsers if there is one you want to leave untouched.
Because TrimyMac only targets the cache folders — not profile data, bookmarks, history, or passwords — the cleanup is safe to run at any time, even while a browser is open. The freed space is immediately available to macOS.
On a typical Mac with two or three active browsers, running a Browser Caches clean in TrimyMac recovers 2 to 6 GB of storage in under 30 seconds. Combined with the App Caches and Dev Tools categories in the same Smart Clean scan, the total reclaimed space is often far larger.
Does Clearing Cache Slow Down Browsing?
Yes — temporarily. This is the most common concern people have, and it is worth addressing directly.
When you clear your browser cache, every page you visit next has to re-download its assets (images, stylesheets, JavaScript files) from the web instead of loading them instantly from disk. For the first few minutes of browsing after a cache clear, pages will feel slightly slower to load — especially image-heavy sites or web apps you visit frequently.
This effect fades quickly. Within 30–60 minutes of normal browsing, your cache will repopulate with fresh versions of the sites you visit most, and performance returns to normal. The key word is fresh — the new cache contains current assets rather than potentially months-old versions that may be mismatched with the latest versions of those sites.
The trade-off is almost always worth it. Stale caches are a leading cause of websites appearing broken, CSS appearing unstyled, or logged-out states persisting even after you log back in. Clearing the cache resets all of that to a clean slate.
Frequently Asked Questions
How do I clear Safari cache on Mac?
The fastest way to clear only the Safari disk cache without touching cookies or passwords is to go to Safari > Settings > Advanced, enable the Develop menu, then click Develop > Empty Caches (or press Option + Command + E).
For a more thorough clear that removes all stored website data including cookies and local storage, go to Safari > Settings > Privacy > Manage Website Data > Remove All.
Does clearing browser cache delete passwords?
No — as long as you only clear cached images and files, your saved passwords are not touched. Passwords in Safari are stored in iCloud Keychain. Passwords in Chrome, Firefox, Arc, and Edge are stored in the browser's own password manager, separate from the cache.
Where you need to be careful is the Clear browsing data dialog in Chromium-based browsers (Chrome, Arc, Edge). If you select the Advanced tab and check "Passwords and other sign-in data", those passwords will be deleted. The default Basic view does not include this option. Simply leave that checkbox unchecked and your saved passwords will remain intact.
How often should I clear my browser cache on Mac?
For most users, clearing the browser cache once a month is sufficient. This prevents caches from growing to several gigabytes while still giving the cache time to be useful between clears.
Clear immediately if you notice a site loading incorrectly, showing outdated content, or behaving unexpectedly after a site update — these are reliable signs of a stale cache conflict. Developers who frequently test local builds should clear far more often, often after each major change.
Where is the Chrome cache stored on Mac?
Chrome's cache on macOS is stored at ~/Library/Caches/Google/Chrome/Default/Cache/. The ~ represents your home folder (e.g., /Users/yourname). If you use multiple Chrome profiles, each profile has its own Cache subfolder — for example, Profile 1/Cache/, Profile 2/Cache/, and so on.
You can navigate there in Finder by pressing Command + Shift + G and pasting the path. Note that this folder is hidden by default — macOS hides the Library directory from the Finder sidebar.
What is the difference between clearing cache and clearing cookies?
Cache stores copies of web page resources — images, CSS files, JavaScript, fonts — to speed up repeat visits. Clearing it forces pages to reload fresh assets from the server. It does not affect your login sessions or site preferences.
Cookies store session tokens, login credentials, preferences, and tracking identifiers set by websites. Clearing cookies logs you out of every website and resets per-site settings. This is much more disruptive to your browsing session.
When your goal is to free up disk space or fix a broken page display, clear only the cache. Only clear cookies when you specifically want to log out of sites or reset your tracked preferences.
Can I clear browser cache for all browsers at once on Mac?
Not through the browsers themselves — each requires you to navigate through its own settings. TrimyMac solves this by scanning Safari, Chrome, Firefox, Arc, and Microsoft Edge cache folders simultaneously. Open TrimyMac, run a Smart Clean scan, and the Browser Caches category will show you the total reclaimable space across all five browsers with a single clean action.
Will clearing browser cache on Mac affect bookmarks or extensions?
No. Bookmarks, extensions, and extension settings are stored completely separately from the cache. In Safari, bookmarks sync through iCloud and are stored in a dedicated database file. In Chrome, Arc, and Edge, bookmarks are stored in a Bookmarks file inside the profile directory, not the cache folder. Extensions are stored in their own directory and are unaffected by any cache operation.
Clearing the cache only removes temporary files your browser has downloaded to speed up page loads. Your browsing setup — bookmarks, extensions, saved tabs, and passwords — remains exactly as it was.
Summary
Browser caches accumulate quietly and steadily, and on a Mac that runs multiple browsers they can consume 10 GB or more of disk space before you notice. Clearing them is safe, fast, and genuinely useful — it resolves display bugs, frees up storage, and resets stale assets that cause sites to misbehave.
For one-off clears, use each browser's built-in Settings menu following the steps above. For regular maintenance without the manual process, TrimyMac's Browser Caches scanner handles all five browsers at once, shows you exactly what it found, and gives you full control over what gets deleted before anything is touched.
